A communication apparatus includes a communication unit. When receiving a request to start communication from a second communication apparatus during communication with a first communication apparatus, the communication unit transmits to the second communication apparatus a communication disabled notification with a retransmission time period indicating a time until the request to start communication again. In addition, when receiving a request to start communication from a third communication apparatus after completing the communication with the first communication apparatus and before receiving the request to start communication sent again from the second communication apparatus based on the retransmission time period, the communication unit does not start data reception from the third communication apparatus so as to give priority to data communication with the second communication apparatus.
